asterisk (*) indicates an excused score (see the Course Information Sheet for
a detailed explanation of an "excused" score). A double dash (--) indicates
an assignment that has not been turned in; this counts as 0 points.
Discrepancies in score display:
If you notice any errors in the
score display, such as an incorrectly entered or missing hw
score, let me know right away and show me the assignment in question.
Errors must be reported within one week from the date the
test/assignment has been returned.

Percentage of course grade.
This exam contributes approximately 1/6 to the course grade.
The current maximal points total (based on two midterms and six hw
assignments) is 420 points and represents about 45 percent of the
points total at the end of the semester. For the complete grading policy,
see the Course Information Sheet handed out
the first week of class.
Letter grade correspondence: For your information, here is an
approximate letter grade correspondence, based on
the current maximal total score of 420 points: a total score above
370/420 corresponds to an A grade (A-, A, A+); 310/420 - 370/420
is a B; 250/420 - 310/420 is a C; and 180/420 - 250/420 is a D.
In case of a simple accounting error (such as an
incorrect addition of scores, or discrepancy between your score on the
exam and the score on the computer grade report), let me know, and I'll
likely take care of it on the spot. If you have a question/complaint about
the grading itself, see me after the 10 am class, or during office hours.
Most errors were not unique, and were graded uniformly; see the Exam Solutions for some common mistakes.
Deadline: The deadline for appeals on Exam 2
is Friday, April 3. (The exam will be returned Monday after the
